Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and, with flour, forms the paste that thickens it.
- Flour
- Thickens the sauce as a starch-based roux paste.
- Tomatoes
- Provide acidity and body to the sauce base.
- Stock
- Supplies the liquid that forms the body of the sauce.
- Curry powder
- Adds aroma and spiced flavour to the sauce.
The step that matters
Adding the flour paste. Flour must be cooked in fat and whisked into the simmering liquid without lumps. Raw flour tastes pasty, and if it is dropped in unmixed it clumps and the sauce thickens unevenly.
Swap the tomato
How well each one fits the dish's main ingredients (butter, onion, flour, pepper):
- Chivefits better
- Okrafits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against butter, onion, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
